Abstract (en)
[origin: EP3219825A1] Provided are an insulation coating composition for an oriented electrical steel sheet, an oriented electrical steel sheet having an insulation coating formed on the surface thereof by using the same, and a manufacturing method thereof, and specifically, it is possible to provide an insulation coating composition for an oriented electrical steel sheet, including 0.1 to 7 wt% of hollow nanoparticles, 0.1 to 5 wt% of ceramic nanofibers, 0.1 to 5 wt% of mesoporous nanoparticles, 30 to 60 wt% of colloidal silica nanoparticles, and 30 to 60 wt% of phosphate, and to provide an oriented electrical steel sheet including an insulation coating produced by the composition on the surface of the oriented electrical steel sheet, including 0.005 to 0.05 wt% of any one element selected from boron (B), vanadium (V), or a combination thereof, 2.6 to 4.3 wt% of silicon (Si), 0.020 to 0.040 wt% of aluminum (Al), 0.01 to 0.20 wt% of manganese (Mn), in which the balance is composed of Fe and other inevitable impurities, and a manufacturing method thereof.
